WILLIAM H. KNOVL'ION, OF TORONTO, ONTARIO, CANADA.

DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 367,412, dated'August 2, 188'7. Application filed November 11, 1886. Serial No. 218,558. (No model.)

To aZZ whom, it may concern.-

Be it known that I, WILLIAM HENRY KNoWLToN, of the city' of Toronto, in the county of York, in the Province of Ontario, Canada, merchant, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a specification.-

The object of the invention is to design a wagon from which its load may bedumped at any desired angle; and it consists, essentially,

in connecting the box of the wagon to the wagon-frame, that it may be turned on a pivot and readily tilted, appliances and connections being provided for facilitating the attainment of this object, substantially as hereinafter more particularly explained.

Figure 1 is a perspective View showing my wagon in its normal position, a portion of? the box being broken away to expose the supporting-timbers. Fig. 2 is a view showing the box tilted to the rear of the wagon. Fig.3 is a'view showing the box tilted to the side. Fig. 4 is a detail of the platform partially broken away, so as to reveal the sixth-wheel, on which it turns.

A is a wagon-box having secured beneath it the supporting-timbers B, the rear end of each I timber being rounded off.

0 is a chute, which, when not in use, is placed underneath the box, between the supportingt'imbers B, and is supported by the platform D.

Outside the boxA, I secure the racks E,

which move in guides f, fastened to the side of the box A.

the rod G, which isjournaled in the supporting-timbers B. The pinions F are designed to engage with the rack E, and are operated by the crank-handle H..-

It will be noticed that I secure on the plat form D two or more pins, d. i The pins d are designed to fit into holes 6 made in the rounded ends of the supporting-timbers B, which are thereby secured firmly in position during the discharge of the coal or other produce.

It will be seen, on reference to Fig. 4, that the platform D is supported on what I term a sixth-wheel, J, constructed on the same principle as an ordinary fifth-wheel.

Ishould have mentioned that on the plat- F are pinions, situated one on each end of form D, I place strips j, which, with the pins cl, before mentioned, are designed to keep the supporting-timbers B in position.

guides to discharge the coal into the chute O.

gare hasps secured to the front of the supporting-timbers B for the purpose of holding the box'in its normal position.

From this description it will be seen that the wagon-box A may be tilted to any desired angle, so as to bring its rear end opposite to the point where it is desired its load should be dumped without the necessity of turning the wagon. I The facility with which the chute can be handled is also an important factor in the device, while the rack-aud-pinion mechanism provided for the dumping of the box enables it to be handled by a single man without either difficulty or extra exertion.

I am aware that a dumping-wagon has been provided with hinged gates independent of the tail-gate, and do not claim such construction. My gates a form apart of the tail-gate, and thus serve a double function.

\Vhat I claim as my invention is 1. The combination, with the timbers B and the wagon-box supported upon and attached thereto, of the racks E, shaft G, journaled in said timbers B, pinion F on'said shaft meshing with the racks, and the crank-handle H,

substantially as and for the purpose specified.

2. The combination, with the sliding chute,

of the wagonbox A, provided at its rear end on each end of said shaft, and the crank-handle H, substantially as and for the purpose stentially as described, and for the purpose specified. specified.

4. The combination, with the sixth-Wheel J Toronto, October 29, 1886. and theplatformD supported thereon nndpror T 7 T vided with pins djof the box A, and the tim- Kb L hers secured to the under side of suidbox and In presence ofhaving rounded ends provided with holes cto CHARLES C. BALDWIN, engage said pins when the box is tilted, sub- Jinn-is E. MAYJIU.
